Bora Guvendik c79da5f211 util/cbmem: Keep original Total Time calculation when no negative timestamps
"Total time" calculation changed after CL 59555 to include
"1st timestamp" value in the calculation. This patch restores original
Total Time calculation where "1st timetamp" is subtracted from
"jumping to kernel". If pre CPU reset timestamps are added (negative
timestamps), "Total time" calculation still includes the pre-reset time
as expected.

1) Before https://review.coreboot.org/c/coreboot/+/59555:
   0:1st timestamp                                     225,897
1101:jumping to kernel                                 1,238,218 (16,316)

Total Time: 1,012,281

2) After https://review.coreboot.org/c/coreboot/+/59555:
   0:1st timestamp                                     225,897
1101:jumping to kernel                                 1,238,218 (16,316)

Total Time: 1,238,178

3) After this patch:
   0:1st timestamp                                     225,897 (0)
1101:jumping to kernel                                 1,238,218 (16,316)

Total Time: 1,012,281

BUG=none
